Connecting to Remote Redis Server

[ccravens]

Pouring through documentation, examples and even the Mosca source for a couple of days now, and have not been able to successfully connect to a remote redis server that requires authentication. I have the following Redis connection URL:

redis://username:password@redis.server.com:9999

and the following documentation specifies the options I have: http://www.mosca.io/docs/lib/persistence/redis.js.html#RedisPersistence

And this is my code:

  var redisurl = url.parse(config['redis'].url, true, true);
  var username = '';
  var password = '';
  if(redisurl.auth != null) {
    username = redisurl.auth.split(':')[0];
    password = redisurl.auth.split(':')[1];
  }
  var server = new mosca.Server({
    backend: {
      type: 'redis',
      redis: require('redis'),
      password: password,
      port: redisurl.port,
      host: redisurl.hostname,
      return_buffers: true // to handle binary payloads
    },
    persistence: {
      factory: mosca.persistence.Redis,
      host: redisurl.hostname,
      port: redisurl.port
    }
  }, function() {
    server.attachHttpServer(app);
  });

And here is what I get as a response:

/Users/ccravens/Business/ossys/Clients/SES/src/ses-proxy/node_modules/ioredis/node_modules/bluebird/js/main/async.js:43
        fn = function () { throw arg; };
                           ^

Error: Ready check failed: NOAUTH Authentication required

Am I missing something?

[mcollina]

can you add the full stacktrace?

[ccravens]

Apologies, after removing the "db:12" attribute from the backend object, there is no stacktrace. It seems to just hang. I have a console statement on "ready" status:

  server.on('ready', function() {
    console.log('Mosca is Running');
    server.authenticate = function(client, username, password, cb) {
      cb(null, (username === '1' && password.toString('ascii') === '2'));
    };
  });

I never see "Mosca is Running" when attempting to connect to the remote server. However when I switch to a local Redis server everything works as expected.

--- edit ---

After running again, there was a stacktrace:

/Users/ccravens/Business/ossys/Clients/SES/src/ses-proxy/node_modules/ioredis/node_modules/bluebird/js/main/async.js:43
        fn = function () { throw arg; };
                           ^
